The Detective Bureau is made up of plain clothes officers who conduct extensive investigations of the numerous cases that have either occurred in or affect the residents and businesses of the City of Signal Hill.

Specific Duties

The Bureau's case assignments are divided among a group of detectives who conduct follow-up interviews of witnesses, victims, and suspects. The investigations may lead detectives to:

Conduct surveillance

Collect additional evidence

Take evidence to the crime lab for further analysis

Work closely with other law enforcement professionals from local, state, and federal agencies

Write and serve search warrants

Filing a Case

Once a case is ready for filing, a detective will present it to the Los Angeles County District Attorney for the issuance of either a criminal complaint or an arrest warrant to take the suspect into custody.
